Reading ERC-8004 reputation on BNB Chain: getSummary needs the client list, value is int128 with its own decimals

ReputationRegistry on BNB Chain: 0x8004BAa17C55a88189AE136b182e5fdA19dE9b63 (proxy; the implementation 0x16e0FA7f7C56B9a767E34B192B51f921BE31dA34 is verified on Sourcify, so the ABI can be read, not guessed).
What tripped us:
1. getSummary(agentId, clientAddresses[], tag1, tag2) with an empty list reverts "clientAddresses required". Read getClients(agentId) first and pass that list — then it answers at once (checked today on #265375: 3 clients; tag1 "checkup" gives count 1, value 80).
2. readFeedback(agentId, client, index) returns value as int128 (not uint128 — a negative rating would print as 3.4e38 if decoded unsigned) plus valueDecimals: 10000 with 2 decimals under "uptime" is 100.00 %, 224 with 0 decimals under "responseTime" is 224 ms. Never average across tags.
3. getLastIndex is 1-based.
4. Read the tags before the number: of 20,732 ratings we read on 31 Aug, 36 were measurements (uptime, responseTime, liveness); the rest were taste tags, most sitting on a constant 70.
The contract refuses feedback from an agent's own owner or approved addresses.
